Description
Technical Field
[0001] This utility model relates to the field of screening device technology, specifically to an automatic sorting and screening device with a valve positioner spring. Background Technology
[0002] An automatic spring sorting and screening device is a piece of equipment used to automatically classify and screen springs, and is used in spring production lines and quality inspection processes.
[0003] Its working principle is as follows: the springs are transported to the detection area by the feeding device; the various parameters of the springs are detected by the sensors; the control system analyzes and judges the detected data and rejects the springs that do not meet the standards, thereby realizing automatic sorting and screening.
[0004] The existing method involves directly feeding the springs to be tested onto the detection plate using a screening machine. This feeding method causes the springs to slide continuously onto the top of the detection plate. During continuous feeding, it is difficult to accurately control the number of springs entering the detection area each time. Too many springs entering at the same time will reduce the accuracy of spring information recognition and thus reduce the working efficiency of the device. To address this, we propose an automatic sorting and screening device for valve positioner springs. Utility Model Content
[0005] One of the technical problems this application aims to solve is that excessive springs continuously entering the detection area lead to a decrease in spring detection efficiency.
[0006] To address the aforementioned technical problems, this application provides an automatic sorting and screening device for valve positioner springs, comprising a screening machine and a camera. A mounting base is provided on the upper front side of the screening machine, and the camera abuts against the upper part of the mounting base. A locking element for locking the camera is provided inside the mounting base. A feeder is provided on the upper right side of the screening machine, and a transfer element for transferring the springs to be tested is provided on the upper right side of the screening machine. A detection disc is provided on the upper left side of the screening machine.
[0007] Preferably, the transfer component includes two transfer rods rotatably connected to the upper right side of the screening machine. The upper end of the right transfer rod is rotatably connected to a transfer rod 2, and the upper end of the left transfer rod is rotatably connected to the middle of the transfer rod 2. A connecting rod is provided at the end of the transfer rod 2 away from the transfer rod 1, and a clamp is provided at the lower end of the connecting rod. A drive component for driving the transfer rods 1 to rotate is provided on the upper right side of the screening machine.
[0008] Preferably, the drive component one includes a fixed base disposed on the upper right side of the screening machine, a motor disposed on the upper part of the fixed base, a crank rod one disposed on the drive end of the motor, a crank rod two rotatably connected to the end of the crank rod one away from the motor, and a crank rod two rotatably connected to the middle part of the transfer rod one on the right side at the end of the crank rod two away from the crank rod one.
[0009] Preferably, the locking component includes a locking plate rotatably connected inside the mounting base, a slider slidably connected inside the locking plate, a locking block provided at the lower part of the camera, a locking groove provided at the lower part of the locking block, the upper end of the locking plate abutting against the inside of the locking groove, a second driving component for driving the slider to move provided inside the mounting base, and a stabilizing component for stabilizing the sliding of the camera provided at the lower part of the camera.
[0010] Preferably, the second driving component includes a push plate slidably connected inside the mounting base. Both the push plate and the mounting base are provided with magnets. A pull rod is provided above the magnet, and the upper end of the pull rod is located below the slider.
[0011] Preferably, the stabilizer includes a stabilizing block disposed at the lower part of the camera, and the upper part of the mounting base has a stabilizing groove, the stabilizing block sliding inside the stabilizing groove.
[0012] Preferably, the connecting rod abuts against the upper part of the clamp, and the clamp has a rotatably connected clamping plate on both the left and right sides inside. A drive spring is provided on the upper end of the clamp away from the connecting rod, and the end of the drive spring away from the clamp is located inside the clamp. Push rods are slidably connected on both the left and right sides inside the clamp, and a baffle is provided in the middle of the push rod. The end of the push rod near the clamp abuts against the outer side of the clamp. The lower left and right sides of the connecting rod have slots, and the upper part of the clamp near the connecting rod abuts against the inside of the slot.
[0013] This utility model has at least the following beneficial effects:
[0014] 1. Through the cooperation between the motor, crank rod one, and crank rod two, the transfer rod one can be driven to rotate periodically. The two transfer rods one push the transfer rod two, which in turn drive the connecting rod and the clamp to approach the feeder to take out the spring to be tested. Then, the transfer rod two is pushed by the two transfer rods one to move towards the detection plate. The transfer rod two drives the connecting rod and the clamp to approach the upper part of the detection plate. The clamp releases the spring to be tested, so that the spring to be tested falls into the loading area on the upper part of the detection plate. This can realize the function of orderly feeding of the spring to be tested.
[0015] 2. Pushing the push plate downwards will move the upper magnet downwards. As the magnet moves downwards, it will pull the lever and slider downwards. When the slider moves, it will cause the locking plate to rotate. The rotation of the locking plate will disengage from the inside of the locking groove. At this time, the camera can be pushed forward to make the stabilizing block slide out of the inside of the stabilizing groove, thereby realizing the function of quick removal of the camera.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Example 1: Please refer to Figure 1-4This utility model provides a technical solution: an automatic sorting and screening device for valve positioner springs, including a screening machine 1 and a camera 11. A mounting base 14 is provided on the upper front side of the screening machine 1, and the camera 11 abuts against the upper part of the mounting base 14. A locking member 4 for locking the camera 11 is provided inside the mounting base 14. A feeder 12 is provided on the upper right side of the screening machine 1. A transfer member 2 for transferring the spring to be tested is provided on the upper right side of the screening machine 1.

[0024] The camera 11 can take pictures of the spring under test, the feeder 12 is used to transport a single spring under test to the upper part of the screening machine 1, the detection plate 13 is used to drive the spring under test to rotate for detection, and the mounting base 14 can provide space for the camera 11 to be installed.
[0025] Furthermore, the transfer component 2 includes two transfer rods 21 rotatably connected to the upper right side of the screening machine 1. The upper end of the right transfer rod 21 is rotatably connected to a transfer rod 22, and the upper end of the left transfer rod 21 is rotatably connected to the middle of the transfer rod 22. A connecting rod 23 is provided at the end of the transfer rod 22 away from the transfer rod 21, and a clamp 24 is provided at the lower end of the connecting rod 23. A drive component 3 for driving the transfer rods 21 to rotate is provided on the upper right side of the screening machine 1.
[0026] The cooperation between the two transfer rods 21 and 22 can form a parallelogram structure between the transfer rod 22 and the transfer rod 21. When the transfer rod 21 rotates, the transfer rod 22 can move and remain parallel to the screening machine 1. The connecting rod 23 can drive the clamp 24 to move.
[0027] Furthermore, the drive component 3 includes a fixed base 31 located on the upper right side of the screening machine 1. A motor 32 is located on the upper part of the fixed base 31. A crank rod 33 is located at the drive end of the motor 32. A crank rod 34 is rotatably connected to the end of the crank rod 33 away from the motor 32. The end of the crank rod 34 away from the crank rod 33 is rotatably connected to the middle of the right transfer rod 21.
[0028] The mounting base 31 provides the foundation height and installation space for the motor 32. The motor 32 can drive the crank rod 33 to rotate. The crank rod 33 is used to pull the crank rod 34 to periodically push the transfer rod 21 to rotate.
[0029] Furthermore, the locking component 4 includes a locking plate 42 rotatably connected inside the mounting base 14, a slider 41 slidably connected inside the locking plate 42, a locking block 43 provided at the lower part of the camera 11, a locking groove 44 opened at the lower part of the locking block 43, the upper end of the locking plate 42 abutting against the inside of the locking groove 44, a driving component 5 for driving the slider 41 to move is provided inside the mounting base 14, and a stabilizing component 6 for stabilizing the sliding of the camera 11 is provided at the lower part of the camera 11.
[0030] The slider 41 can slide inside the lower part of the locking plate 42. When the slider 41 slides up and down, it pushes the locking plate 42 to rotate. The rotation of the locking plate 42 can abut against the inside of the locking groove 44. The locking block 43 is used to connect the camera 11.
[0031] Furthermore, the second driving component 5 includes a push plate 53 that is slidably connected inside the mounting base 14. Both the push plate 53 and the mounting base 14 are provided with magnets 52. A pull rod 51 is provided above the upper magnet 52, and the upper end of the pull rod 51 is provided below the slider 41.
[0032] The lever 51 can pull the slider 41 to move. The two magnets 52 are opposite each other with the same pole. The push plate 53 can drive the magnets 52 to move downward. When the magnets 52 move, they can pull the lever 51 to move downward.
[0033] Furthermore, the stabilizer 6 includes a stabilizing block 61 disposed at the lower part of the camera 11, and a stabilizing groove 62 is provided on the upper part of the mounting base 14, and the stabilizing block 61 slides inside the stabilizing groove 62.
[0034] The stabilizing groove 62 allows the stabilizing block 61 to slide in one direction and prevents it from moving upward and detaching from the mounting base 14, thereby stabilizing the sliding of the camera 11.
[0035] When the device is running, the feeder 12 will continuously supply the springs to be tested. The motor 32 starts and drives the crank rod 33 to rotate. The crank rod 33 pushes the crank rod 34 to periodically push the transfer rod 21 to rotate. At this time, the two transfer rods 21 can push the transfer rod 22 to keep parallel with the screening machine 1, while driving the connecting rod 23 and the clamp 24 to approach the feeder 12 to take out the springs to be tested. Then the transfer rod 22 is pushed by the transfer rod 21 to move towards the detection plate 13. The transfer rod 22 drives the connecting rod 23 and the clamp 24 to approach the upper part of the detection plate 13. The clamp 24 will release the springs to be tested, so that the springs to be tested fall into the loading area on the upper part of the detection plate 13. This can realize the function of orderly feeding of the springs to be tested. Then the detection plate 13 rotates and drives the springs to be tested to approach the camera 11 for data acquisition and judgment.
[0036] Pushing the push plate 53 downwards can move the upper magnet 52 downwards, increasing the elastic force between the two magnets 52. As the magnets 52 move downwards, they can pull the lever 51 and the slider 41 downwards. When the slider 41 moves, it can drive the locking plate 42 to rotate. The rotation of the locking plate 42 will disengage from the inside of the locking groove 44. At this time, the camera 11 can be pushed forward, causing the stabilizing block 61 to slide out of the inside of the stabilizing groove 62. This enables the camera 11 to be quickly removed.
[0037] Example 2: Please refer to Figure 5 Based on Embodiment 1, this utility model provides another technical solution: the connecting rod 23 abuts against the upper part of the clamp 24, and the clamp 24 is rotatably connected to the left and right sides of the interior. The upper end of the clamp 25 away from the connecting rod 23 is provided with a driving spring 27, and the end of the driving spring 27 away from the clamp 25 is provided inside the clamp 24. The clamp 24 is slidably connected to the left and right sides of the interior. The middle part of the push rod 26 is provided with a baffle 28, and the end of the push rod 26 near the clamp 25 abuts against the outer side of the clamp 25. The lower left and right sides of the connecting rod 23 are provided with slots 29, and the upper part of the clamp 25 near the connecting rod 23 abuts against the inside of the slots 29.
[0038] The clamping plate 25 can rotate. When the clamping plate 25 rotates, it can compress the drive spring 27 to retract. The push rod 26 can slide to push the clamping plate 25 to rotate. The baffle 28 is used to prevent the push rod 26 from slipping out of the inside of the clamp 24. The slot 29 provides the engagement and locking space for the clamping plate 25. Pushing the two push rods 26 to compress the clamping plate 25 to rotate, the upper ends of the two clamping plates 25 can disengage from the inside of the slot 29 when rotating, and compress the drive spring 27 to retract. Then the clamp 24 can be pulled down to replace it with a new clamping plate 24 so that the connecting rod 23 can be inserted. Releasing the two push rods 26 causes the drive spring 27 to rebound and push the clamping plate 25 to rotate. The clamping plate 25 engages inside the slot 29 and pushes the push rod 26 back to its original position, so that the clamping plate 24 can be quickly replaced when needed.
